An accessory is selectively coupled in a first position or a second position to a portable electronic device. The accessory includes a touch unit and a heat dissipation unit. The touch unit is configured to be touched by a user to apply a contact force. An area of the touch unit to be touched by the user is defined as a contact point. When the accessory is in the first position, the touch unit detects a location of the contact point and outputs a control signal to the portable electronic device. The heat dissipation unit comes in contact with a heat source of the portable electronic device when the accessory is in the second position.
Legal claims defining the scope of protection, as filed with the USPTO.

2. The accessory for the portable electronic device as claimed in claim 1 , further comprising a body, wherein the portable electronic device and the heat dissipation unit are mounted to the body, wherein the body includes a front edge, a rear edge opposite to the front edge, a first side, and a second side opposite to the first side, wherein the front edge is adapted to face the user, wherein the rear edge faces the portable electronic device when the accessory is in the first position, the touch unit is mounted to the first side, wherein the heat dissipation unit is mounted to the second side, and wherein the second side faces and is connected to the portable electronic device when the accessory is in the second position.
3. The accessory for the portable electronic device as claimed in claim 2 , wherein the touch unit is connected to the portable electronic device by a wired or wireless connection when the accessory is in the first position.
4. The accessory for the portable electronic device as claimed in claim 3 , wherein the touch unit includes a touch pad and at least one connecting portion configured to be connected to the portable electronic device, wherein the touch pad protrudes beyond the first side of the body, wherein the at least one connecting portion protrudes beyond the rear edge of the body, and wherein the at least one connecting portion is electrically connected to the portable electronic device when the accessory is in the first position.
5. The accessory for the portable electronic device as claimed in claim 4 , wherein the at least one connecting portion is a pogo pin.
6. The accessory for the portable electronic device as claimed in claim 2 , wherein the heat dissipation unit includes a contact member, at least one fan, and at least one conductive tube connected between the contact member and the at least one fan, wherein the contact member and the at least one conductive tube are made of metal, wherein the contact member protrudes beyond the second side of the body, wherein the contact member comes in contact with the heat source of the portable electronic device when the accessory is in the second position, such that heat generated by the heat source is dissipated out of the body via the at least one conductive tube and the at least one fan.
7. The accessory for the portable electronic device as claimed in claim 6 , wherein the body includes a plurality of vents defined in each of the front edge and the rear edge, and wherein the plurality of vents in the rear edge is aligned with the at least one fan.
8. The accessory for the portable electronic device as claimed in claim 6 , wherein the contact member has cross sections identical to cross sections of an opening of the portable electronic device, and wherein the contact member is configured to contact with the heat source of the portable electronic device via the opening when the accessory is in the second position.
9. A combination comprising: a portable electronic device that generates a heat source when in operation, wherein the portable electronic device includes a bottom side having an opening; and an accessory selectively coupled in a first position or a second position to the portable electronic device, wherein the accessory includes a touch unit and a heat dissipation unit, wherein the touch unit is configured to be touched by a user to apply a contact force, wherein an area of the touch unit to be touched by the user is defined as a contact point, wherein when the accessory is in the first position, the touch unit detects a location of the contact point and outputs a control signal to the portable electronic device, wherein when the accessory is in the second position, the heat dissipation unit faces and is connected to the bottom side of the portable electronic device, and the heat dissipation unit contacts with the heat source of the portable electronic device via the opening.
10. The combination as claimed in claim 9 , wherein the portable electronic device includes a cap door mounted to the bottom side to selectively cover the opening, wherein the cap door reveals the opening when the accessory is in the second position, such that the heat dissipation unit contacts with the heat source of the portable electronic device via the opening.
11. The combination as claimed in claim 9 , wherein the accessory further includes a body, wherein the portable electronic device and the heat dissipation unit are mounted to the body, wherein the body includes a front edge, a rear edge opposite to the front edge, a first side, and a second side opposite to the first side, wherein the front edge is adapted to face the user, wherein the rear edge faces the portable electronic device when the accessory is in the first position, the touch unit is mounted to the first side, wherein the heat dissipation unit is mounted to the second side, and wherein the second side faces and is connected to the portable electronic device when the accessory is in the second position.
12. The combination as claimed in claim 11 , wherein the touch unit is connected to the portable electronic device by a wired or wireless connection when the accessory is in the first position.
13. The combination as claimed in claim 12 , wherein the touch unit includes a touch pad and at least one connecting portion configured to be connected to the portable electronic device, wherein the touch pad protrudes beyond the first side of the body, wherein the at least one connecting portion protrudes beyond the rear edge of the body, and wherein the at least one connecting portion is electrically connected to the portable electronic device when the accessory is in the first position.
14. The combination as claimed in claim 13 , wherein the at least one connecting portion is a pogo pin.
15. The combination as claimed in claim 10 , wherein the heat dissipation unit includes a contact member, at least one fan, and at least one conductive tube connected between the contact member and the at least one fan, wherein the contact member and the at least one conductive tube are made of metal, wherein the contact member protrudes beyond the second side of the body, wherein the contact member comes in contact with the heat source of the portable electronic device via the opening when the accessory is in the second position, such that heat generated by the heat source is dissipated out of the body via the at least one conductive tube and the at least one fan.
16. The combination as claimed in claim 15 , wherein the body includes a plurality of vents defined in each of the front edge and the rear edge, and wherein the plurality of vents in the rear edge is aligned with the at least one fan.
17. The combination as claimed in claim 15 , wherein the contact member has cross sections identical to cross sections of the opening of the portable electronic device.
